Aesthetically the gun/technology focus of gnb just fits him a lot better than the dark magic knight vibe of drk in my opinion. He'd have an interesting Fray though (I think they all would) (frick, now I want to write about that)

Man, I didn't even SEE the comparison between Isurd and Urianger, lmao. You're so right. Maybe I picked up on it unconsciously and that's why I was so bent on ast Isurd.
